25 teams, one day: in Nantes, Daher teams build their own Copilot agent

Industrial AI training: in Nantes, 25 Daher teams attend an AI Show, then a Copilot Agentathon. Each team builds its own agent in a single day.

On 4 November 2026, AI Sisters ran an AI Show + Agentathon day for Daher in Nantes, from 9am to 5pm.

‍

25 teams learned to prompt in the morning, then built their own AI agent on Copilot in the afternoon. The leaderboard ran live on the AI Sisters platform.

‍

Nantes is the fourth day of the Daher series in 2026, after Toulouse, Tarbes and Paris. Same format, new teams.

‍

Running a proven format again, this time in Nantes

‍

Daher rolls out AI site by site. Toulouse in February, Tarbes in September, the support functions in Paris in October. In Tarbes, teams loved the format, and Daher chose to run it again as is in Nantes.

‍

The challenge for AI Sisters: take 25 teams from discovering Copilot to building their own agent, in a single day.

‍

Act on the same day

‍

No inspiration day without follow-through. Every team had to leave with an agent it built itself.

Stay in the everyday tool

‍

Everything happens in Copilot, which teams already have. No extra platform to adopt after the training.

Keep the bar high from one site to the next

‍

Fourth day of the series. The format had to deliver in Nantes just as it did in Tarbes and Paris.

What if it were you?

Your teams have Copilot but don’t really use it yet?
‍
We build a day with you where every team leaves with its own agent.

Plan my Agentathon

Our AI training programme for Daher’s Nantes teams

‍

One day from 9am to 5pm, in two parts: the AI Show to understand, then the Agentathon to build. Two AI Sisters trainers, Titouan and Arnaud, went from table to table with the teams.

‍

01

The opening AI Show

LLMs and the art of prompting, then Copilot features inside Microsoft 365 apps. With hands-on exercises, such as a five-line summary for a director.

Phase 1: building one agent together

All teams build the same agent, step by step, on the AI Sisters platform. Each round earns points, and the leaderboard updates live on screen.

Phase 2: everyone builds their own agent

Each team moves on to its own agent, for a need in its own job. Trainers move between tables to unblock prompts and instructions.

AI use cases covered in Nantes

‍

From a well-built prompt to a business agent: the day followed the path each team can retrace on its own the next morning.

Tools used: Copilot

‍

Prompting well

‍

→ Understand how an LLM works

→ Structure a prompt to get a usable answer

→ Summarise a topic for a director in five lines

‍

Copilot inside the apps

‍

→ Copilot in everyday Microsoft 365 tools

→ The features to know before building an agent

‍

Business agents

‍

→ A shared agent built round by round

→ Then one agent per team, for a need in its own job

→ A tool built by the people who will use it
